### **How many Mondays are in 1980?**

1980 has 52 Mondays. The first is Monday, January 7, 1980.

### **When does the first full Monday-to-Sunday week of 1980 start?**

The first Monday of 1980 is Monday, January 7, 1980. ISO week 1, the week that holds the first Thursday of January, starts on Monday, December 31, 1979.

### **Why start the week on Monday?**

The ISO 8601 standard and most of Europe count Monday as the first day of the week. Saturday and Sunday then sit together at the end of each row, which makes weekends easy to see and lines up with ISO week numbers.
